What is one impact that climate change can have on coral reefs?

Warming temperatures have caused stress on corals causing them to expel the zooxanthellae, its symbiotic algae. The coral loses its colour provided by the algae. This process is known as bleaching. Without the photosynthesis performed by the zooxanthellae, the coral polyps will not receive glucose, glycerol and amino acids that are essential to give it the energy to eat zooplankton and will die.

How might the presence of antecedent soil moisture impact the stores and flows of a drainage basin?

With the presence of antecedent soil moisture, water will not be able to infiltrate into the soil store or the percolate to the groundwater store. There will be an increase of surface water which could lead to the river channel exceeding its bankfull discharge and a flood to occur.

What were some of the political, physical and social barriers faced a Syrian refugee’s while attempting to migrate to EU countries?

Political Barriers Obtaining the correct Schengen visa to enter the countries stopped these refugees from entering. This left many people by the boarders while countries decided if there would allow them to become asylum seekers in their country. Physical Barriers As refugees were trying to get to Greece many opted to take an illegal boat across the Mediterranean Sea leading to a high volume of casualties and fatalities. Social Barriers Many refugees did not speak the language of the destination, had a different religion and had a different standard of gender equality. This cause friction between the locals and the refugees causing the number allowed into the countries to be limited.
